It equals 53X- a number is squared when it is multiplied by itself, so 7X by 7X = 49X. 2X by 2X =4X, so 49X + 4X is 53X.
if its x(squared) its 7x(cubed) if its 2xX its 14x(squared)
No, It's a a quadratic equation because you have X squared.
49/4 or 12.25
y = 3x + 21x2 = 3x(1 + 7x)
21 X squared over 5
It is (7x+3)(x+9) when factored
If you mean 5x^2 -7x +2 = 0 then it is a quadratic equation with solutions of x = 2/5 or x = 1
5x2+ 7x + 2 = (x + 1)(5x + 2).
5x2+7x = 12 5x2+7x-12 = 0 (5x+12)(x-1) = 0 x = -12/5 or x = 1
49x2 - 84x + 36 = (7x - 6)(7x - 6) or (7x - 6)2
It is a quadratic expression and it is (7x+6)(7x+6) when factored
7x + 8
5(7x^2y + 6x^2 + 8)
12x and then the squared. (the little two)
It is: 12x2-7x-12 equals (4x+3)(3x-4) when factored
7x + y = 8 Subtract 7x from each side of the equation: y = -7x + 8
You would factor 2x2 + 7x + 6 into (2x + 3) (x+2)
7x(3x3 - 2x2 + 5x + 1)
